The impact of the earth’s increasing surface temperature is meaningful in itself because it will affect the planet. But global warming will cause other reactions on the planet to happen that will have a vast effect on earth. The warming of the planet changes rainfall patterns, causes further coastal erosion, lengthens the growing season in some regions, melts glaciers and ice caps, and changes the effects of some infectious diseases. Some of the changes have already been happening and could increase in severity, which would increase the impact that they have on people and the planet.

Changes in Weather

For a majority of places, global warming will trigger hotter days more often and cooler days less often. The biggest warming increase will occur over land. Longer and hotter heat waves will become more common. Severe storms, strong floods and bitter droughts may increase in severity as rain patterns change. Hurricanes may increase in intensity because of warmer ocean surface temperatures.

Global warming is likely to cause bigger storms that are more destructive which lead to an increase in precipitation. A lot of what affects climate change is natural factors but human induced global warming has led to climate change in many areas.

Many natural things like latitude, elevation, water that is close by, ocean currents, typography, vegetation and prevailing winds play into the climate of a particular place or region.

Although it is tough to point at one singular weather event and say that it was caused by global warming, evidence is pointing towards it having an effect on the weather.

Droughts, extreme rain events and heat waves have increased in the last 50 years and global warming most likely contributed to this trend.

How Does Global Warming Affect Humans?

The influences of global warming on human health vary depending on the region. Some climate changes that have occurred because of global warming specifically could impact humans. For instance, increased temperatures, severe weather storms, precipitation extremes, increase in summer droughts, increase in growing season and the sea level rising are climate changes that can expose humans to certain harmful outcomes.

Exposure to things like extreme heat, poor air quality (because of ozone in atmosphere or other fossil fuels in atmosphere), reduced food and water quality, changes in infectious agents that can harm humans and population displacement. That exposure can lead to heat-related illness, cardiopulmonary illness, food or water contamination which can lead to disease, vector borne disease, mental health problems and stress.

Poor air quality can negatively affect the human respiratory and cardiovascular system. Changes in the climate can have an effect on the air we breathe. With changing weather patterns it has changed levels of pollutants like ground level ozone.

Natural wildfires are predicted to increase because of climate change and global warming. This would increase emissions of particulate matter and ozone, which can lead to negative health effects. These can increase the chances of premature death and chronic cardiovascular and respiratory issues.

The increase in greenhouse gasses led to an increase in both average and extreme temperatures. This is expected to lead to more deaths from heat and a potential decrease in deaths from the cold. Certain communities that could be affected by these changes are children, the elderly and poor people who don’t have the resources to get out of the heat.

When it is hotter in the summer or colder in the winter than the average seasonal temperature it can create increased levels of illness and death. It can compromise the body’s task to regulate the internal temperature or it can cause other health complications. The loss of internal temperature control can lead to a snowball of illnesses like heat cramps, heat exhaustion, heatstroke and hyperthermia in extreme heat, and hypothermia and frostbite in the extreme cold.

Extreme temperatures can also make chronic conditions worse like cardiovascular disease, respiratory disease, and diabetes-related conditions.

Positive Effects of Global Warming

With the negative downside of global warming there is also some positive effects that could come from the increased temperature on earth. Fewer people dying from extreme cold in winter is a major positive since the temperature is rising and average winter temperatures are likely to rise.

Certain crops could be grown further north in the United States. A longer growing season, which could be lengthening because of climate change, allows farmers to grow produce for a longer time which could increase their profits.

It also could lead to less energy being needed to heat buildings in the winter.

North Pole Temperature and What It Indicates

The North Pole temperature has risen in the winter in recent years and caused increased evidence that global warming is happening in one of the coldest places on earth. In December 2016, the North Pole and the Arctic saw record high temperatures and record-low ice extent. The decrease in ice mass in the Arctic and around the world has led to an increase in sea level, because of melted ice. The increase in sea level could lead to the potential displacement of towns and cities that are close to the edge of oceans.
